Hello,

I am upgrading my 72g tank to a 90g. I will be starting out with an Icecap 4 x 110w system on acrylic mirror retro. I will be adding 2 Metal Halide lights to this setup and was unsure what I wanted to go with. The tank is a mixed reef with just a couple of sps corals(Pocillapora). I plan to add more sps corals such as montipora, acropora, stylophora. I am not sure if I should go with just 2 x 175w since I already have 4 x 110w vho or should I go with the 2 x 250w Iwasaki. If I went with the 250s' would that be too much for some of the soft corals, leathers, and mushrooms if I decided to get some? Also, if you were to go with the 250 would you use 4 vhos or would you just use two?

Thanks for your input
